UNITED STATES PATENT OFFICE EDWIN M. LINES, OI DEDHAM, MASSACHUSETTS, ASSIGNOB- TO BIRD SON, INC., 01 EAST WALPOLE, MASSACHUSETTS, A CORPORATION 01 MASSACHUSETTS BUILDING INSULATING MATERIAL AND CONSTRUCTION Application filed January 11; 1932. Serial No. 585,868.

it is common to space the studding in the walls so that the 2" X4 studs are spaced 16", or 18" on centers. Variations in materials, construction, or both, frequently result in variations in spacing amounting to an inch or even more, plus or minus, andthus the spaces between studs may he say 13 to 15", or 16 to 18", respectively, for studs intended to be spaced 16", or 18 on centers.

It is the object of this invention to provide an eflicient heat insulating material and construction which may be readily uti- 20 lizedand assembled without cutting or fitting of the individual units thereof, and at I the same time an insulating material which is capable of accommodating itself to the wide variations in structure just referred to.

In the accompanying illustrative draw- Tig. 1 is a perspective view of a portion of a wall constructed in accordance w1th this invention and incorporating therein the 1mproved insulating material described here- Fig. 2 is a cross-sectional view of a portion,

of. the wall; and

Fig. 3 is a perspectlve view of an 1nd1v1dual insulating unit in collapsed form and with a portion of the exterior surfacing broken away to better show the interior construction thereof. v I

Referring to the drawing in which likenumerals represent like-parts,a portion of a building wall is shown in Figs. 1 and 2, the building having an exterior wall sheathing 2, spaced parallel studs 4, and an interior-wall sheathing 5. Between each pair of studs is placed a vertical series of heat insulating units generally designated at 6 with the vertically adjacent units 6 in each series slight 1y spaced by separating members 8. In Figs. 1 and 2 the insulating units are permanently held in position by nails 10, though such nails are not strictly necessary for, due to the multiple folded construction of the individual insulating units, the natural resiliency of the folded units holds them in place. In Fig. 3 is shown an individual unit of the preferred type made up of a sheet of corrugated board'12 with six parallel fold lines scored therein as indicated'at a, b, c, d, e, and f. The sheet 12 has attached thereto, as by staples 14, a smaller sheet of corrugated board 16 having two fold lines scored therein and designated 9 and h. The unit as thus described provides, when expanded and installed, three separate insulating air spaces as clearly shown in Fig. 2. The elongated hexagonal central portion has wing-like exa tension members 18 extending from the opposite sides thereof. Each of said winglike extensions 18 has a stud-abutting por-' tion 20 hingedly attached thereto. The stud abutting-portions are of such a size that they serve to space the elongated hexagonal air cell approximately centrally between the inner and outer wall sheathing. The width of portions 20 is made somewhat less than the minimum width of standard 2"X4" mate- 'rial commonly used for studding. Thus the insulating units can be readily flexed and thrust into position with the ends of the portions 20 abutting the outer wall sheathin 2 and with the opposite connectin fol ed edges clearing the inner wall sheat ing 5.

It has been found in preferred form of insulating unit made in accordance with this inventlon can readily accommodate a range of sizes or variations; including at least 4 inches, so that ordinarily but one size unit is required for any standard and usual construction. The units when in collapsed condition (Fig. 3) lie flat and may be stacked or packed in convenient sized bundles for the required shipping and handling, but upon application may be flexed and expanded by an operator grasping the extensions and pushing them towards each other, thus flexing the resilient material on fixed with" the spacers therebetween. Then,

practice that the if desired, units may be nailed as above mentioned and the inner wall sheathing applied.

Though the insulating unit, in its preferred form, includes the stud abutting por- 5 tions 20, these portions 20 may be omitted and the units, without such portions 20, nailed in position with the nails 10 in the manner shown in Fig. 2. If it is not desired to nail the modified units in place they may be positioned as in Fig. 2, or they may be reversed, back side to front, so that the terminal margins of the unit abut the exterior wall sheathing 2.

It is evident that an insulating unit of the herein described type may be made up so that each of two separate pieces of material provides one wing-like extension as well as one long side of the elongated hexagon, or, the unit may be made a single folded piece of material.
